Shipping conditions update: ambient shipping
This product will be delivered at ambient temperature instead of chilled – this is by design. Extensive stability testing confirmed that our products are suitable for shipment under ambient conditions and maintain expected quality.
Why the change?
It’s part of our commitment to more sustainable packaging solutions, with ambient deliveries using eco-friendly materials such as recyclable cardboard instead of polystyrene.
What you need to know
Ambient shipments come clearly marked on the delivery note.
No ice will be included in ambient shipments, but mixed orders (ambient and cold-chain items) will still arrive with ice packs to protect temperature-sensitive products.
Warranty coverage remains fully valid, aligned with our validated shipping method.
Please store the product as per the datasheet instructions upon receipt.

Cathepsins L V K and H are essential cysteine proteases that serve important functions in protein catabolism. These proteases participate in proteolytic processes by digesting proteins into shorter peptides and amino acids. Cathepsin L also known as CTSL typically has a molecular mass of about 25-35 kDa and is expressed in various tissues such as the liver spleen and placenta. Cathepsin K plays a similar role in bone resorption and is highly expressed in osteoclasts. Cathepsin V and Cathepsin H meanwhile have distinct tissue distributions with cathepsin V often found in the thymus and testis whereas cathepsin H's expression spans across different cell types contributing a vast array of biological functions.
Biological function summary
Cathepsins regulate cellular homeostasis and modulate various physiological processes. These proteases perform their functions within the lysosomal compartment although they can also participate in extracellular matrix remodeling and other non-lysosomal roles. Cathepsin K for example is part of the cathepsin protein family and aids in degrading collagen therefore playing a pivotal role in bone turnover and resorption. Cathepsins can act independently or in some cases are part of larger enzyme complexes enhancing their proteolytic activity to handle different substrates driven by the physiological demand.
Pathways
Cathepsins key in the lysosomal degradation pathway and influence other signaling cascades like the apoptotic pathway. The regulation of these pathways often involves interactions with other proteins such as pro-apoptotic members of the Bcl-2 family facilitating cell death under certain conditions. Cathepsin L contributes to the antigen processing pathway linking it to the immune response. Cathepsin K on the other hand acts closely with structural proteins like collagen in the bone metabolism pathway highlighting its significance in skeletal development and maintenance.
Altered cathepsin activity closely associates with conditions like osteoporosis and cancer. Cathepsin K upregulation can lead to excessive bone degradation seen in osteoporosis while aberrant cathepsin L expression relates to cancer progression and metastasis due to its role in degrading extracellular matrix components facilitating tumor invasion. In osteoporosis interactions with matrix metalloproteinases further enhance bone matrix breakdown exacerbating disease symptoms. In cancer the relationship between cathepsin L and the urokinase-type plasminogen activator system highlights its role in promoting malignancy and suggests potential therapeutic targets.
